Interpretation

This data depicts a subset of approx. 209,000 yelp businesses in ten metropolitan areas within the US and Canada. As can be seen in the figure businesses that accept creditcards, usually have more reviews especially in the coastal areas in the West and the East.

Discussion

Discussion of key findings: The dataset depicts that businesses are rather ready to accept creditcards and have, on average, more ratings than those who don't. Based on the colors it appears debateable if this results in a better rating. At least it appears as though this factor has no significant effect on the rating. However questions remain whether this dataset is representative. Also questions have to be raised regarding a hidden variable. Maybe the higher amount of ratings is due to the location of the restaurant or any other factor. Here statistical testing and correlation analysis would be necessary.
